This paper discusses the likely evolution of the trade and environment issue in the World Trade Organization after the upcoming ministerial meeting in Singapore this December. It makes a number of points. Progress within the GATT/WTO on this issue looks likely to be slow and painfully...

We study a growth model with an environmental asset which is a source of utility and an input to consumption and production. The stock of this asset follows its own ecological dynamics, which are affected by economic activity. We study the implications of an approach to ranking sequences of...

The 1930's American Dust Bowl was an environmental catastrophe that greatly eroded sections of the Plains. Analyzing new data collected to identify low-, medium-, and high-erosion counties, the Dust Bowl is estimated to have immediately, substantially, and persistently reduced agricultural land...

The relationship between economic growth and the environment is not well understood: we have only limited understanding of the basic science involved and very limited data. Because of these difficulties it is especially important to develop a series of relatively simple theoretical models that...

We assess the role of land markets on factor misallocation in Ethiopia--where land is owned by the state--by exploiting policy-driven variation in land rentals across time and space arising from a recent land certification reform. Our main finding from detailed micro data is that land rentals...

Despite technological advances, an individual car's emissions still cannot be measured reliably enough to impose a Pigovian tax. This paper explores alternative market incentives that could be used instead. We solve for second-best combinations of uniform taxes on gasoline, engine size, and...

Our analysis melds two traditional approaches to promoting quality. The first is restoring the stock of quality. The second is curbing its flow of deterioration. Although both approaches are widely used in real world settings, analytic models have tended to focus on one strategy or the other. We...

We study which policy tool and at what level a majority chooses in order to reduce activities with negative externalities. We consider three instruments: a rule, that sets an upper limit to the activity which produces the negative externality, a quota that forces a proportional reduction of the...
